Description

[0001] The present invention relates to the technical field of soil remediation, and in particular to a soil remediation device for soil and water conservation and a remediation method thereof. Background Art

[0002] Soil remediation is a vital environmental engineering technology that aims to restore soil damaged by pollution, degradation or over-exploitation to its original healthy state or near-natural state. This process involves a variety of technical means, such as physical remediation (such as excavation, solidification / stabilization), chemical remediation (such as leaching, redox), biological remediation (such as phytoremediation, microbial remediation) and integrated remediation technology, and the specific choice depends on the type of pollutants, the degree of pollution, soil characteristics and remediation goals.

[0003] After searching, the invention patent with Chinese patent number CN112222175B discloses a soil remediation device for contaminated soil. Compared with the prior art, the invention patent with Chinese patent number CN112222175B includes a vehicle body and wheels. The lower left corner of the vehicle body is rounded, and a soil turning device is arranged at the rounded corner position of the vehicle body. A medicine discharging device is arranged between the two wheels on the right side. The soil turning device includes a roller and a connecting plate. The connecting plates are movably installed on both sides of the roller. The other end of the connecting plate is fixedly connected to the rounded corner surface of the vehicle body. A trigger mechanism is arranged in the rounded corner surface of the vehicle body. A medicine storage box, a fixing rod and a linkage plate are fixedly installed on the bottom surface of the vehicle body. The soil remediation device for contaminated soil works through the soil turning device and the medicine discharging device. When the user performs soil remediation, he only needs to push the vehicle body to move. At this time, the roller will rotate, and the folding plate and the soil turning block will flip and loosen the soil, so that it can better penetrate when the medicine is applied. At the same time, when the roller rotates, intermittent medicine addition can be performed in the medicine storage ring.

[0004] However, in the actual use of the above device, when the device is spreading the repair agent, the repair agent is simply spread on the soil. These repair agents preferentially contact the shallow soil and are absorbed, while the deeper soil can only absorb a small amount of repair agent, or even no repair agent. Therefore, the repair effect of the device on the deeper soil is poor. At the same time, when the soil repair device sprays the repair agent, it directly extracts it from the bottom of the medicine storage box, lacking stirring measures for the repair agent to prevent precipitation. This causes some sediments to settle at the bottom of the medicine storage box. Due to the lack of external force, these sediments are difficult to float up and participate in stirring, so they are directly extracted and sprayed out, causing the proportion of components in the repair agent to change, the repair agent becomes thinner, affecting the effect of the repair agent, and easily causing the soil repair to be not thorough enough. Therefore, a soil repair device for soil and water conservation and a repair method thereof are proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the repair agent in the prior art is simply spread on the soil, and the repair agent is directly extracted and sprayed, which causes the proportion of components in the repair agent to change, the repair agent becomes thinner, affects the effect of the repair agent, and easily causes the soil repair to be not thorough enough.

The soil remediation device for soil and water conservation according to claim 8, characterized in that: The stirring rod (27) is movably connected to the movable plate (24); one end of the stirring rod (27) away from the movable plate (24) is fixedly connected to the first stirring plate (20); the first stirring plate (20) is fixedly connected to the second stirring plate (21) on the side close to the first support plate (1); the second stirring plates (21) are provided in multiple groups and are symmetrically distributed; the first support plate (1) is fixedly connected to a rotating shaft (22) on the side close to the medicine storage box (2); the rotating shaft (22) is connected to the stirring plate (20) and the stirring plate (20) is fixedly connected to the second stirring plate (21); The first support plate (1) is fixedly connected to the rotating rod (19) on one side thereof, and the second spring (26) is fixedly connected to the stirring rod (27) on the other side thereof, and the first support plate (1) is fixedly connected to the stirring rod (27) on one side thereof, and the first support plate (1) is fixedly connected to the movable plate (24) on one side thereof, and the fixing ring (29) is fixedly connected to the fixing slide rod (30), and the threaded groove (28) is slidably connected to the fixing slide rod (30).

10. The soil remediation method for soil and water conservation according to claim 1, characterized in that: The steps include: Step 1: Connecting the first support plate (1) to an external traction machine, when the first support plate (1) stays on the land to be repaired, by rotating the threaded rod (18), the rotation of the threaded rod (18) drives a plurality of V-shaped plates (16) to be inserted into the land that has been rotary tilled in advance, and the rotation of the threaded rod (18) allows the V-shaped plates (16) to be adjusted according to the depth of rotary tillage; Step 2: by adjusting the V-shaped plate (16), the spraying pipe (13) follows the adjustment of the V-shaped plate (16), the repair liquid flows into the spraying pipe (13), and is sprayed out through the spray head on the spraying pipe (13), so that the spraying pipe (13) sprays the repair liquid on soil layers of different depths, and the spray head on the upper part of the spraying pipe (13) sprays the land surface, and the V-shaped plate (16) can separate the soil during the movement process to prevent the soil from blocking the spraying pipe (13); Step 3: by loading the repair liquid into the medicine storage box (2), the movement of the traction machine causes the second wheel (4) to drive the rotating rod (19) to rotate, the rotation of the rotating rod (19) drives the convex block (23) to rotate, the rotating convex block (23) drives the stirring rod (27) to move up and down, so that the stirring rod (27) drives the first stirring plate (20) to move up and down inside the medicine storage box (2), thereby stirring the repair liquid in the medicine storage box (2); Step 4: The stirring rod (27) moves up and down, so that the threaded groove (28) on the stirring rod (27) slides on the fixed slide rod (30), and the stirring rod (27) rotates during the process of moving up and down through the threaded groove (28) and the fixed slide rod (30). The rotating stirring rod (27) drives the second stirring plate (21) on the first stirring plate (20) to stir the repair liquid inside the medicine storage box (2).
